Gorillas are large primates that belong to the family Hominidae. They are native to the forests of Africa and are divided into two species: the Eastern gorilla and the Western gorilla. Gorillas are known for their strong build, with adult males weighing up to 450 pounds. They primarily eat leaves, stems, and fruits, making them herbivores. These animals live in social groups called troops, typically led by a dominant male known as a silverback. Gorillas are intelligent and exhibit complex behaviors, including using tools and communicating through vocalizations and gestures. They play a crucial role in their ecosystem by helping to disperse seeds.
